B 65 D 5/02 ( 52) Index at acceptance B 8 P A ( 54) CARTON BLANKS AND CARTONS MADE THEREFROM ( 71) I, BRIAN GEORGE BAKER, a British subject, of 32, Shaftsbury Circle, South Harrow, Middlesex, England, do hereby declare the invention, for which I pray that a patent may be granted to me, and the method by which it is to be performed, to be particularly described in

and by the following statement:-

This invention relates to carton blanks and to the cartons formed from them.

According to one aspect of the present invention, there is provided a carton blank comprising a substantially rectangular portion having first, second, third and fourth flaps along one major side and, along the opposite major side, first, second and third flaps opposite said first flap on said one major side, a fourth flap opposite said second flap on said one major side, fifth, sixth and seventh flaps opposite said third flap on said one major side and an eighth flap opposite said fourth flap on said one major side, hinge lines being provided across the blank from between the adjacent flaps on said one major side, these hinge lines extending respectively to between said third and fourth, said fourth and fifth and said seventh and eighth flaps on said opposite major side.

According to another aspect of the present invention, there is provided a carton formed from the blank as defined in the preceding paragraph.

For a better understanding of the invention and to show how the same may be carried into effect, reference will now be made, by way of example, to the accompanying drawings, in which:Figure 1 is a plan view of a carton blank, Figure 2 is a perspective view showing a cartin formed from the blank shown in Figure 1, and illustrates how goods and packing can be inserted in the carton whilst leaving space for later insertion of a further integer between the goods, Figure 3 is a view similar to Figure 2 and showing the goods and packing in the carton, Figure 3 A is a perspective view of a 50 second carton which is to be inserted in between the goods packed in the first carton, Figure 4 is a perspective view illustrating how flaps of the first carton are folded to 55 secure the second carton in place in the first carton and to seal the goods in the first carton, and Figure 5 is an exploded perspective view illustrating how a third carton containing 60 further goods can be inserted within the open second carton at a later stage of packing the goods.

Referring firstly to Figure 1, the blank of the first carton comprises a substantially 65 rectangular portion 13 having four flaps 1-4 along one major side and eight flaps 5-12 along the opposite major side The flaps 5, 6 and 7 are opposite the flap 1; the flap 8 is opposite the flap 2; the flaps 9, 10 and 70 11 are opposite the flap 3; and the flap 12 is opposite the flap 4 A hinge line 14 extends across the portion 13 from between the flaps 1 and 2 to between the flaps 7 and 8 A hinge line 15 extends 75 across the portion 13 from between the flaps 2 and 3 to between the flaps 8 and 9.

A hinge line 16 extends across the portion 13 from between the flaps 3 and 4 to between the flaps 11 and 12 An end flap 17 80 is provided on the end of the portion 13 adjacent the flaps 4 and 12, this flap 17 serving as a stich flap to be stitched to the opposite end of the portion 13, which forms four side walls of the carton, or it 85 can be glued.

The flaps 1-4 form the base of the carton and the flaps 5-12 are at the top of the carton when the carton is assembled as shown in Figures 2-5 90 2 1 567 705 2 The carton is intended to house goods such as loud speaker cabinets as well as further goods, such as loud speaker grilles, which are to be inserted at a different time and at a different place from the cabinets themselves.

Figure 2 shows two cabinets 18 being inserted into the carton, suitable blocks 19 of, for example, polystyrene, being placed around upper and lower edges of the cabinets to serve as packing and protection for the goods.

It will be seen that the flaps 5 and 7 and the flaps 9 and 11 are each respectively longer than each of the flaps 6 and 10, the flaps 5, 7, 9 and 11 substantially corresponding to the width of each speaker cabinet 18.

As shown in Figure 3 A, a second carton 20, which is open at its top, is provided for insertion into the first carton in between the two cabinets 18.

Figure 4 shows how the flaps of the first carton are closed so as to be able to seal the containers 18 in it It will be seen that the second carton 20 has been positioned in the first carton and its flaps 20 A and B have been folded outwardly over the adjacent packing blocks 19 End flaps 20 C of the second carton 20 are folded inwardly of the carton 20 and then the flaps 6 and 10 of the first carton are folded into the inside of the second carton 20, the flaps 6 and 10 being of slightly less width than the width of the carton 20 The flaps 8 and 12 are folded onto the tops of the packing blocks 19 and then the flaps 5, 7, 9 and 11 are folded over so that the carton assumes the form shown in the lower part of Figure 5 The width of each flap 5, 7, 9 and 11 is half the total width of the first carton so that the pairs of flaps 5 and 11 and 7 and 9 meet when folded towards each other so that sealing tape, glue or staples, for example, can be provided to seal the cabinets in the first carton The second carton 20 remains open and the whole package can then be transported to another location, perhaps in another country, for a separate package containing for example, the loud speaker grilles, to be inserted in the second carton in the middle of the first carton Figure 5 shows a third carton 21 which is of slightly smaller dis 5 mensions that the second carton 20 so that the carton 21 can be slipped inside the carton 20 without having to interfere with the already sealed-in cabinets 18, the carton 21 containing the speaker grilles, for example The carton 21 can then be secured by suitable means within the carton 20.
